Your lens appears nearly identical to a Toyo/T.O.U. Optics/Five Star lens that I have. I believe it comes from one of the lesser know makers such as Cima, Makina or someone very obscure. I am fairly certain it is not from Tokina, Kino, Tamron, or Sigma. During the mid eighties, lenses like this one were available from discounters for as little as $99 US. Mine is very lightly built with some elements retained by spring clips instead of threaded retainers.

Boomer,

Your Tokina SZ-X is another interesting bird as I have seen a lens of that specification and general build labeled as Sigma and Tamron also. I have one in Tamron Adaptall 2 configuration. It was part of a two zoom kit with a common instruction sheet. I think I've posted about that kit here previously.

Thanks for all of the info and discussion. The photo of the other lenses appear to be much newer version than mine. Are the Tokina and Hanimex on Nikon mount? Notice the rabbit ear on my lens, indicating an older version of the Nikon mount lens.

I actually had a choice between the Magnicon and another similar lens by "Image". I chose this one, as the glass looks cleaner, and has extra filter included (for the same price)

Another queation is about a Tokina 50-250mm lens. Anyone knows about this lens' quality? It has been sitting in the store for months and no one bought it (for $40). Is it a decent lens (also for Nikon mount)?

Did they make lenses for export in China, Korea, etc in the 1980s?
My lens does not said "Japan", and has f stop of f/4.5-5.5 on it.

Who made the Hanimex lens? I remember that it seems to be related to Praktika camera. Is it from East Germany?

Do you find the sharpness of the lens adequate? I thought it is a good buy for a $30 lens. I also bought a Vivitar 28mm F/2.8 prime lens, and I am also happy with the results. Here are 2 photos taken with the Vivitar:

I would just shoot a few close distances at 80,100,135&200mm at all stops to f11 or f16(two sets @ one and five meters),then shoot a near distance of 10-15 meters....and if you wish to shoot longer distances...then a far distance set of 75 meters,then a set at a distance of 4-6 or more kilometers.

Find it's sweet spots at various focal lengths and that will give you a bit of insight of the lens abilities,and a starting point to work from.

BTW...what Nikon/s are you shooting?_________________Trust that little voice in your head that says "Wouldn't it be interesting if...." And then do it.

1- Tokina 50-250 is VERY GOOD (one of the best tele lenses at that period - whatever the trade mark
Tokina lenses are Japan made

Hmm, the lens has the same style grip as a Hanimex I had, made in Korea and a Sigma also:

The Hanimex was very good, whilst the Sigma was crap. But it easily be neither

I have a Sigma which looks to be almost identical to yours:

They do look similar to aniramca's Magnicon, although I suspect they are newer. Mine was a Nikon mount before I robbed it for parts, but it shows the selected aperture in a little window, and is lacking the coupling fork that the Magnicon has. These Sigmas also have a distinct step in the lens barrel at the end, which is absent in the Magnicon:

A photo of the Magnicon lens

I took a few photos with this lens, but ended up using it for parts for a mount conversion of a different lens. Optically, it was noticeably worse than my Vivitar Series 1 70-210 (V3) f2.8, so aside from this one being smaller & lighter, I didn't have any real reason to keep it around.... well, keep it around intact that is. I think I paid $10 for it, and it had an old faded sticker on it marking it at $120.
